There used to be a number of search engines with significant market share. Those employed as SEOs often expend huge energy trying to unravel the algorithm as the companies are not transparent with how they run, due to the proprietary nature of their business and their desire to prevent manipulation of search engine results. This discipline is known as Search Engine Optimization (SEO).Įarly search engines results were based largely on page content, but as websites learned to game the system through advanced SEO practices, algorithms have become much more complex and search results returned can be based on literally hundreds of variables.Įach search engine now uses its proprietary algorithm that weighs many complex factors such as relevancy, accessibility, usability, page speed, content quality, and user intent in order to sort the pages in a certain order. Since most users only browse the top results, it is particularly important for a website to rank high enough for certain queries to ensure its success in terms of traffic.Ī whole science developed in the last few decades to make sure that a website, or at least some of its pages, “scale” the ranking to reach the first positions. The higher a website is ranked in the SERP, the more relevant it should be to the searcher’s query. Then, when a user queries a search engine, relevant results are returned based on the search engine's algorithm. This constant and recursive process is known as indexing, and is necessary for a website to be displayed in the SERP. Once all data has been fetched by the bots, the crawler adds it to a massive online library of all discovered URLs.

To help bots do their crawling work in a more efficient way, larger websites usually submit a special XML sitemap to the search engine that acts as a roadmap of the site itself.

Hyperlinks are parsed to find internal pages or new sources to crawl when they point to external websites. These small bots can scan all sections and subpages of a website, including content such as video and images. First a spider/ web crawler trawls the web for content that is added to the search engine's index. A search engine performs a number of steps to do its job.
